Print nicely please

$res = 99.87354618113;
printf("%.2f%%", $res );

returns: "99.87%"
Nice!

$res = "100";
printf("%.2f%%", $res );

returns: "100.00%"
Ugly!

Anybody who knows how to make it print 100% instead of 100.00%??
Can I (and how) use number_format()?

Solutions welcomed.

Hm, I think .2f will always give to numbers after the ".". So you could check, if the last 3 chars are ".00" and then just cut it off.

Still looking for a more solid function.

Time to stop looking and write your own.
There isn't anything better than what he
described in terms of built-in functionality.

PHP is doing its best at least. Can't do everything.
